differential separation

differential separation

[‚dif·ə′ren·chəl ‚sep·ə′rā·shən]
(chemical engineering)
Release of gas (vapor) from liquids by a reduction in pressure that allows the vapor to come out of the solution, so that the vapor can be removed from the system; differs from flash separation, in which the vapor and liquid are kept in contact following pressure reduction.

The most preferred gel characteristics for successful differential separation of single-strand conformers in the range of 200-300 bp, where the method should be most sensitive and reliable, are 12% acrylamide [3] and cross-linking ratios (%C) between 1 and 3 [4].
From these experiments it follows that PEG at 5 g/L is suitable for differential separation of single-stranded DNA fragments in the range of 150-528 nucleotides in 12% acrylamide gels with %C = 2.
